Description

FIELD OF THE INVENTION

The present invention relates to systems and methods for monitoring equipment in a container yard.

BACKGROUND OF THE INVENTION

Container yards will refer to shipping terminals and/or container terminals that may be transfer points for containers between marine and/or land-based shipping of the containers. The containers come in five sizes ranging from twenty feet (20
FT) to fifty three feet (53 FT) long, and when filled, may weigh up to 110,000 pounds, or 50,000 kilograms, making them impossible to move, except by machinery referred to herein as container handlers.

Maintaining the container handlers and their status reporting devices can be a significant expense. As container yards are often required to run inventory systems for the entire terminal autonomously, being able to maintain equipment
efficiently without disrupting production becomes increasingly important, creating a need to automatically monitor the inventory moved by these vehicles.

The need to automatically monitor the container handlers mechanical systems, and the state of the status reporting devices communicating what the container handler is doing is further fueled by the observation that overall container yard
efficiency tends to improve with knowing the status and/or location of each container handler and of each container moved by that container handler.

Additionally, illicit use of the container handlers may be minimized by use of operator identification as part of the automatic monitoring.

BRIEF SUMMARY OF THE INVENTION

A processor is disclosed that may be configured to respond to a received status report for a vehicle in a container yard, and/or for a status reporting device configured to monitor the vehicle state of containers it is moving in the terminal.
The processor may respond to the received status report by creating a system log and/or a system action request. The system action request may include a fault condition problem report and/or a maintenance schedule request for the vehicle and/or the
status reporting device. The system action request may stimulate a system action performed on the vehicle and/or the status reporting device.

The processor automates generating of the responses to the received status reports, thereby providing a fundamental tool to reduce down time for the vehicles and improve their support of container transfer operations in the container yard.

The vehicle may be at least one member of a container handler list and/or a member of a non-container handler list. The container yard may a transfer point for at least one container moved by at least one of said members of said container

installation package configured to instruct the computer to install the program system. The server may be configured to deliver the program system and/or the installation package to the computer. The server can also record log file data from the
equipment installed and alert the user of maintenance events over a web interface or e-mail message protocol.

Fault events may be related to specific ways in which the vehicles and/or the status reporting devices may experience inefficiencies or obstacles to performing their tasks. For example, the fault event may include at least one member of an
event list including an engine coolant event, an oil pressure event, an alternator voltage event, a battery voltage event, a headlight switch event, a seatbelt engagement event, a diesel particulate filter trap event, a collision event, an operator
identity event and/or a container discrepancy event. Non-fault events can include engine hours elapsed for required maintenance, high fuel consumption events.

Events that may be critical to a correctly functioning, status reporting device for container movement, may also be reported. This may include reporting events in the handling of containers such as a twistlock event, a landed signal event, a
container weight sensor reading, a container gain or loss sensor event, a fifth wheel latch/unlatch event, a spreader trolley position change event, a spreader hoist height position change event, an equipment reverse movement event, and/or a gantry or
equipment movement event.

The processor may be further configured to receive the status report via a wireless transceiver and/or a removable memory device interface and/or a wireline network interface. The processor may further include the wireless transceiver and/or
the removable memory device interface and/or the wireline network interface.

The processor may send the system action request to a maintenance dispatch node to at least partly create the system action. The request may be sent via the wireless transceiver and/or the removable memory device interface and the wireline
network interface.
